      Table 1 Name and Description

      Parameter	Description
      Name	Specifies the alarm rule name. The system generates a random name, which you can modify. Example value: alarm-b6al

   2. Select a monitored object and set alarm rule parameters.

      Table 2 Parameters

      Parameter	Description	Example Value
      Resource Type	Specifies the type of the resource the alarm rule is created for.	Elastic Cloud Server
      Dimension	Specifies the metric dimension of the selected resource type.	ECSs
      Monitoring Scope	Specifies the monitoring scope the alarm rule applies to. You can select Resource groups or Specific resources. NOTE: If Resource groups is selected and any resource in the group meets the alarm policy, an alarm is triggered. If you select Specific resources, select one or more resources and click to add them to the box on the right.	Specific resources
      Select Group	This parameter is mandatory when Monitoring Scope is set to Resource groups.	-
      Method	There are two options: Use template or Create manually.	Create manually

      Alarm Policy	Specifies the policy for triggering an alarm. If you set Resource Type to Website Monitoring, Log Monitoring, Custom Monitoring, or a specific cloud service, whether to trigger an alarm depends on whether the metric data in consecutive periods reaches the threshold. For example, Cloud Eye triggers an alarm if the average CPU usage of the monitored object is 80% or more for three consecutive 5-minute periods. If you set Resource Type is to Event Monitoring, the event that triggers the alarm is an instant event. For example, if event improper ECS running occurs, Cloud Eye triggers an alarm.	-
      Alarm Severity	Specifies the alarm severity. Valid values are Critical, Major, Minor, and Informational.	Major

      Notification Object	Specifies the object that receives alarm notifications. You can select the account contact or a topic. Account contact is the mobile phone number and email address of the registered account. A topic is used to publish messages and subscribe to notifications.

   4. Click Create.

After the alarm rule is created, if the metric data reaches the specified threshold, Cloud Eye immediately informs you that an exception has occurred.
